Ferguson made three enforced changes with Bailey Wright making his debut at the back as Morgan was on international duty. Parry replaced Treacey who is away with Ireland and Coutts came in for Russell.
Preston were held until just before the break when yound Danny Major was brought down in the box. Callum Davidson converted the penalty and Preston then took the initiative in the second half.
Matty James volleyed in the second before he was brought down in the box. This time Hayes took the penalty to put Preston three up. Hayes then banged in another before young substitute KIng raced onto a long ball to put home his first goal for the Whites.
Preston now enter into the draw for the second round which takes place tomorrow.
